Insecurity in ATM-Based Passive Optical Networks

Tags:
optical networking

Overview This paper considers the security of an ITU standard for ATM-based passive optical networks. First, it shows that the standard's encryption algorithm, called churning, has an effective 8-bit key length and thus is trivial to break with exhaustive keysearch. Second, it shows that the authentication mechanisms have significant weaknesses. The conclusion is that these measures should not be relied upon to provide security.

Staff mobile devices increase security risk

Gartner's Heiser believes encryption will become one of the most important factors in securing portable devices, predicting "in five years all laptops will be encrypted". Turner said: "Encryption for laptops will be essential eventually.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
